Comments | Cool Toy, lousy Robot though. You might be able to do a Servo Hack for the drive motors, but it would be a Tight fit. |
Please note the gears (total of two) between each of the wheels. These are how the single motor drives all the wheels on each side.
Also note the assortment of levers connecting the wheels to the
body. This allows the wheels on the left of the picture to
pivot up and down as the Sojurner goes over obstacles.
Side view with showing the action of the wheels and levers as
the Sojurner goes over an obstacle.
The Sojurner in action!
Front View. Note: The manufacturer somehow thoght that the APXS goes on
the front of the Sojurner.
Rear View
The undercarriage. The gear box for the motor is underneath the
panel on the left side of the picture.
The "Solar Panel" has been removed. Note the 4 AA nicad batteries
on the upper left portion of the Sojurner.
Top view of the Sojurner with the "Solar Panel", batteries, and the
electronics cover removed. The red you see in the middle is the radio
antenna, and the board you see is the electronics for the radio.
Same view as above, but with the battery compartment removed.
This is the undercarriage of the Sojurner with the motor compartment
panel removed. Note that there is only one motor for the Sojurner,
and there is no cam assembly in place to make it turn in reverse. (
Rats!!!)
Same picture as above, but with two standard Airtronics servos in place.
Please note that these servos Do NOT fit inside the motor
compartment. It is possible that two wing servos might fit
in the compartment, but even so, it is probable that re-installing the
cover would be impossible.
